Xueba, I beg you to go and escort him quickly!

"No! Obviously many students find it difficult!"

.......

Chapter 234

He Junfei stood in front of his eyes, stunned for a long time.

He looked bad.

At this time, Zhou Xiu'e also opened her mouth to make up the knife, "It is true that their principal came in person and said it in front of me and Lao Xu!"

He Junfei, "%%￥#￥￥..."

"I see, Auntie, you don't have to repeat it again!"

Yue Pingting said, "He Junfei, you should go back to study! Don't worry about what happened to Xu Heng, don't make trouble for yourself!"

"Although you have made telescopes before! But... I think Xu Heng will succeed. As for what you said, I think Xu Heng must have taken everything into consideration!"

"Otherwise, he wouldn't have done it."

Although Yue Pingting made a bet with Xu Heng, in front of outsiders, Yue Pingting still ignorantly sided with Xu Heng and supported him unconditionally.

He Junfei sighed, "Okay!"

He Junfei probably understood what Yue Pingting meant.

But He Junfei didn't intend to leave directly, but faced up to the difficulties and went up again.

"I want to learn from Xu Heng!"

Since you can't beat it!

Then join!

He Junfei's thinking changed again after experiencing this fluctuation.

Xu Heng looked at He Junfei who came up again, "?"

He Junfei, "Learn from you, I want to learn from you, and then sum up experience to see where I went wrong."

"When I was in junior high school, I tried to make a telescope..."

"..."

He Junfei and Xu Heng probably chatted.

While giving Xu Heng a hand, they chatted.

While chatting, He Junfei completely shut up.

He opened his mouth wide, and his whole body was not well.

It was because he realized that the refracting telescope that Xu Heng was going to make was so big that it would be as tall as a person.

He Junfei, "Xu Heng, you, what do you want to see?! Do you really want to see the planet?!"

Xu Heng was very calm, "If you don't look at the planet, what's the point?"

He Junfei, "!!!"

What Xu Heng said made sense, but He Junfei heard that his whole body was about to crack.

Look at the planet!

Is this what a telescope made out of these things can see?

???

Xu Heng, are you okay?

He Junfei couldn't believe it, he looked left and right, "Can this add up to 1000 yuan?"

Han Honghu said at this time, "Almost!"

He Junfei, "!!!"

Use 1000 yuan to do tens of millions of things?

"Xu Heng! How dare you!"

"hiss……!"

He Junfei gasped, suppressing all his doubts, followed Xu Heng, and kept busy.

"Xu Heng, how do you get it calibrated? You don't have an inspection instrument, do you?"

Xu Heng smiled, "We can judge whether the optical axis is adjusted properly through actual observation."

"Find a clear night with a relatively quiet atmosphere, use the highest magnification of the telescope, and count the diameter of the primary mirror in millimeters."

"Look at a star, Polaris if you don't have an equatorial mount. Put the star point in the center of the field of view of the eyepiece, this will reduce the aberrations caused by the eyepiece, adjust the focus carefully, from out of focus to in focus, then in focus .”

"Whether the star image is solid, thin, and sharp in focus, and whether the diffraction rings are concentric circles after defocusing..."

Xu Heng's foundation is very solid.

It's not comparable to a nerd like He Junfei.

He was stunned for a moment.

"I, this, this, this..."

He Junfei was ashamed.

In fact, he didn't quite understand Xu Heng's meaning at all.

He just knew that it needed to be adjusted, but he didn't really study it in depth.

After all, this thing cannot be tested during the exam...

This is He Junfei's most fatal flaw.

So it eventually led to him talking a lot on paper.

But this time, He Junfei once again realized the huge gap between him and Xu Heng!

If it was just grades at the beginning, then it was just a two-dimensional gap, but now, he clearly felt that there was a three-dimensional gap between him and Xu Heng, or even more.

Xu Heng simply applied the knowledge in his life.

And it is the kind of seemingly understatement application, but it makes life very colorful.

Next door, Wang Duofang looked for He Junfei several times.

She was very puzzled, isn't her son studying from books?Why are there no more people all of a sudden!

Suddenly, she noticed that in the attic of Xu Heng's house, He Junfei was helping Xu Heng move things, busy with things.

She was dumbfounded.

"My silly son! How can you do such a thing! How do I teach you! You will have to use your brain to work in the future! You, this, this, this... are so mad`~!"

Wang Duofang wanted to find He Junfei, to bring him home, but was stopped by Lao He!

"What are you going to do!"

Wang Duofang, "I'll call my son back! Why should our son be a coolie for their family!"

Old He roared, "Didn't you see that my boss is helping there too?!"

Wang Duofang, "%￥#￥..."

Lao He, "I know how to study every day! I'm dead! Let him get in touch with Xu Heng more, it's good to learn more!"

Wang Duofang just wanted to talk about what to learn from being with Xu Heng.

But suddenly she realized that Xu Heng was no longer the ignorant Xu Heng from before!

He is now an existence that even He Junfei can't afford to climb!

Wang Duofang once again looked at the certificate on the wall, lowered her head, and sighed, "Hey..."

Without Wang Duofang's obstruction, He Junfei has been going to Xu Heng's house for the past few days.

Learning is also put down.

From Xu Heng's place, He Junfei really learned a lot.

Just kidding, He Junfei is now working as an assistant next to a physics professor or even a physicist, so naturally he has learned a lot.

During the break, He Junfei looked at the gradually formed telescope, which even he himself found inconceivable.

"Crack-"

Looking at the telescope frame that was taller than a person, he took a photo and posted it in the group.

"Unexpectedly, the most common thing we have actually made the telescope frame! The next thing is the lens! As long as we can get it done, maybe we can really see the planets in space!"

"!!!"

The group exploded.

Everyone is on winter break now!

The crowd was very lively.

Many people looked at the photos and couldn't help frowning, "???"

"Are you sure this is a telescope? It looks like a water pipe!"

He Junfei, "It's just water pipes! There are also these things, iron frames and so on, all of which we can often see!"

"I don't believe it can be done either! But it's really done now!"

"I won't tell you anymore, I will continue to grind the glass mirror! I will continue to share the results with you later!"

He Junfei put down his phone and continued to work.

Xu Heng, "The accuracy error of the parabola is less than one ten-thousandth of a hair. It must be ground carefully. We can have a try after all these are done!"

It happened that the weather was sunny during this time, which was very suitable for observation.

After repeated grinding several times.

It was the evening of the next day.

Xu Heng stared at the mirror seriously, frowning deeply, "Give it a try!"

These four words have been uttered, and in an instant, everyone's faces were filled with joy.

Success or failure is here!

Xu Heng, "Let's go! Come back to calibrate at seven or eight o'clock in the evening! If you can, you can watch the stars!"

At dinner, everyone was fine, looking up at the top of their heads as they ate.

They were afraid that something might happen to the telescope that they took a few days to make.

Xu Heng rolled his eyes at Xu Yueshan, "Dad! Why don't you bring a bowl of rice up there and watch?"

Xu Yueshan, "%￥%#￥..."

Xu Heng looked at Zhou Xiu'e again, "Mom! Let my dad sleep with the telescope!"

Zhou Xiu'e, "I look like it!"

Xu Yueshan shrank his neck, "It's okay! No way!"

"Hahaha……"

The whole family roared with laughter.

Finally stayed up until seven o'clock in the evening.

All crammed into the small attic.

Xu Yueshan, Zhou Xiu'e, Yue Pingting, Yueba Yuema, and He Junfei, even Lao He and Wang Duofang all came to watch curiously.

At this time, Xu Heng held the telescope and began to carefully and carefully calibrate it.

Everyone looked at Xu Heng with a dazed expression, including He Junfei.

Wang Duofang kept asking He Junfei, "Junfei, where does Xu Heng specialize? What does it mean?"
